Vue.js Axios Delete then

Introduction

When working with Vue.js, sometimes you need to delete data from the server using Axios. In this case, you'll want to use the delete method of Axios. Once the delete request is sent to the server and a successful response is received, you may want to take some action, such as displaying a success message to the user or updating some data in your Vue component. This is where the then function comes in.

Syntax

Here is the basic syntax for making a delete request with Axios and handling the response using then:

axios.delete(url)
  .then(response => {
    // handle success
  })
  .catch(error => {
    // handle error
  });

In this example, url is the endpoint you want to send the delete request to. The then function takes a single argument, which is a callback function that will be executed if the request is successful. The response argument contains the response data sent from the server. If there is an error, the catch function will be executed with the error argument containing the error data.

Handling success

In the then function, you can handle the successful response from the server. Here is an example of updating a variable in your Vue component:

axios.delete(url)
  .then(response => {
    this.myVariable = response.data;
  })
  .catch(error => {
    // handle error
  });

In this example, this.myVariable is updated with the data sent from the server in the response. You can also display a success message to the user using a Vue component or some other method.

Handling errors

In the catch function, you can handle any errors that may occur during the delete request. Here is an example of displaying an error message to the user:

axios.delete(url)
  .then(response => {
    // handle success
  })
  .catch(error => {
    alert('Error deleting data!');
    console.log(error);
  });

In this example, an alert is displayed to the user with the message "Error deleting data!" if there is an error. The error data is also logged to the console for debugging purposes.

Conclusion

Using the delete method of Axios and the then function in Vue.js makes it easy to delete data from the server and handle the response. By taking advantage of these tools, you can streamline your development process and make your code more efficient.
